H. AN INTRODUCTION TO PHARHACOLOGY. 

 By H. fl. Richter, M. D. 



INTRODUCTORY. 



While the following experiments will more forcibly im- 

 press the student's memory with the action of the drugs 

 under consideration than any didactic lecture possibly 

 could, this must be considered as of secondary importance. 

 The real object is to teach pharmacological technique to 

 place the student in a position where he can at any time 

 in the future demonstrate experimentally to his own satis- 

 faction the activity or inactivity of any drug, and its modus 

 operandi. 



With this object in view, experiments have been 

 chosen which can readily be performed by the student 

 himself. No attempt is made to show the various actions 

 of each drug used, but, instead, the most conspicuous and 

 easily demonstrated action of each is utilized. Considera- 

 ble time is expended on the reflex arc, because the action 

 of drugs on its different elements is most readily demon- 

 strated. 



Little can be found concerning the doses to be used in 

 experiments. In order to save time and trouble, the dose 

 to be used in each of the following experiments is given.
